Omron D4GL-4CFG-A-NPT Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4CFG-A-NPT is an interlock solenoid locking switch with dual-pole, single-throw (DPST) configuration designed for panel disconnect applications. This component features a 24VDC supply voltage, 240VAC switching capability, and 102kgf holding force. The product is classified as obsolete, necessitating identification of active equivalent models to maintain system functionality and ensure continued availability for maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The D4GL-4CFG-A-NPT has been superseded by the D4SL-N series, specifically the D4SL-N3CFG and D4SL-N3CFG-N models. Both substitute parts maintain functional equivalence based on the following critical parameters:

Substitution Criteria:

• Solenoid locking type with panel disconnect actuator
• DPST-NO/NC + DPST-NC circuit configuration
• Screw terminal termination style
• IP67 ingress protection rating
• Operating temperature range of -10°C to 55°C
• Moisture sensitivity level 1 (Unlimited)
• Approval certifications including CE and TUV

Key Differences: The D4SL-N series substitutes feature enhanced current ratings (1.5A AC, 220mA DC versus 750mA AC), increased holding force (133kgf versus 102kgf), expanded voltage compatibility (120VAC/125VDC in addition to 240VAC operation), and 1/2" NPT conduit threading versus M20. Both substitute models are active products with current manufacturing status and full inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N3CFG and D4SL-N3CFG-N models are qualified substitutes for the obsolete D4GL-4CFG-A-NPT. Selection between the two active alternatives should be based on inventory availability and application-specific requirements:

D4SL-N3CFG: 889 units in stock. Suitable for standard panel disconnect applications requiring DPST switching with enhanced current capacity and holding force.

D4SL-N3CFG-N: 793 units in stock. Functionally equivalent to D4SL-N3CFG with identical electrical and mechanical specifications.

Both substitutes provide expanded compliance certifications (CCC addition) and improved performance characteristics (higher current ratings and holding force) compared to the original part. The D4SL-N series maintains compatibility with the core functional requirements of panel disconnect solenoid locking applications while offering active product status and assured long-term availability.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N3CFG or D4SL-N3CFG-N directly replace D4GL-4CFG-A-NPT in existing installations?

A: Yes. Both substitute models maintain identical circuit configuration (DPST-NO/NC + DPST-NC), actuator type (panel disconnect), termination style (screw terminal), operating temperature range (-10°C to 55°C), and ingress protection rating (IP67). Mechanical mounting and electrical interface compatibility must be verified for the specific application, particularly regarding conduit thread size differences (M20 versus 1/2" NPT).

Q: What are the key performance differences between the original and substitute parts?

A: The D4SL-N series provides higher AC current rating (1.5A versus 750mA), DC current capability (220mA), increased holding force (133kgf versus 102kgf), and expanded voltage compatibility (120VAC/125VDC in addition to 240VAC). These enhancements represent performance improvements suitable for demanding panel disconnect applications.

Q: Is there a functional difference between D4SL-N3CFG and D4SL-N3CFG-N?

A: No. Both models share identical electrical specifications, mechanical design, and performance characteristics. Selection between them is based solely on inventory availability and packaging preferences.

Q: What compliance certifications apply to the substitute parts?

A: Both D4SL-N3CFG and D4SL-N3CFG-N carry CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage than the original D4GL-4CFG-A-NPT (CE, cULus, TUV).

Q: Are there any installation considerations when transitioning from D4GL-4CFG-A-NPT to D4SL-N series?

A: Conduit thread size differs (M20 to 1/2" NPT), requiring verification of mounting hardware compatibility. Electrical connection points and screw terminal specifications remain consistent. Mechanical envelope and panel cutout dimensions should be confirmed for the specific application.
